Pulse Handling Capabilities of
Vishay Dale Wirewound Resistors
INTRODUCTION
Power wirewound resistors have steady-state power and voltage ratings which indicate the maximum
temperatures that the units should attain. For short durations of 5 seconds or less, these ratings are
satisfactory; however, the resistors are capable of handling much higher levels of power and voltage
for short periods of time (less than the cross-over point). For instance, at room temperature the RS005
has a continuous rating of 5 W, but for a duration of 1 ms the unit can handle 24 500 W, and for 1 μs
the unit can handle 24 500 000 W. The reason for this seemingly high power capability is the fact that
energy, which is the product of power and time, is what creates heat; not just power alone. Vishay Dale
can provide solutions for your application if provided with information detailed on page three.

WIREWOUND RESISTORS
Vishay Dale
Short Pulses (Less Than the Cross-Over Point Time Duration)
For short pulses, it is necessary to determine the energy applied to the resistor. For pulses less than the cross-over point,
Vishay Dale engineering assumes all of the pulse energy is dissipated in the resistance element (wire). In order for the resistor
to maintain its performance characteristics over the life of the product, Vishay Dale bases analysis and recommendations on
the amount of energy required to raise the resistance element to + 350 ºC with no heat loss to the core, coating, or leads.
The cross-over point is the time where significant energy starts to be dissipated not only in the wire itself but is now being
dissipated into the core, leads, and encapsulation material. This is the point where the pulse is no longer considered a short
pulse, but is now considered a long pulse.
The pulse handling capability is different for each resistor model and value, as it is based on the mass and specific heat of the
resistance element. Once the power and energy have been defined, Vishay Dale can determine the best resistor choice for the
application.
Cross-Over Point
An example of an RS005 500 Ω resistor at room temperature:
Required information:
ER = Energy rating of a given model, resistance value, and ambient temperature. Provided by Vishay Dale, ER = 6.33 J.
PO = The overload power capability of the part at 1 s. The overload power capability of an RS005 for
1 s, 10 x 5 W x 5 s = 250 Ws/1 s = 250 W
Cross-over point (s) = ER (J)/PO (W)
6.33 J/ 250 W = 0.0253 s.
The cross-over point for the RS005 500 Ω resistor at room temperature is approximately 25.3 ms.
Long Pulses (Cross-Over Point to 5 Seconds)
For long pulses, much of the heat is dissipated in the core, leads, and encapsulation material. As a result, the calculations used
for short pulses are far too conservative. For long pulse applications, the short time overload ratings from the datasheets are
used. Note that repeated pulses consisting of the short time overload magnitude are extremely stressful and can cause some
resistor styles to fail.
• To find the overload power for a 5 s pulse, multiply the power rating by either 5 or 10 as stated on datasheet
• To find the overload power capability for 1 s to 5 s, convert the overload power to energy by multiplying by 5 s, then
convert back to power by dividing by the pulse width in seconds
• For pulse durations between the cross-over point and 1 s, use the overload power computed for 1 s
Example
1. What is the overload power for an RS005resistor?
From the datasheet, the RS005 is rated at 5 W and will take 10 times rated power for 5 s: 10 x 5 W = 50 W
2. What is the energy capability of the RS005 for 5 s?
For 5 s, the energy capability is: 50 W x 5 s = 250 W·s or J
3. What is the overload power capability of the RS005 for 1 s?
For 1 s, the overload power capability is 250 W·s / 1 s = 250 W
4. What is the energy capability of the RS005 for 0.5 s?
For 0.5 s, the energy capability is 250 W x 0.5 s = 125 W·s or J

Equally Spaced Repetitive Pulses
When calculating pulse handling capability for repetitive pulses, the average power as well as the individual pulse energy
must be considered. This is because the average power establishes some average heat rise on the part, which uses up
some percentage of the part’s energy capability. That portion of the energy not used by average power is then available
to handle the instantaneous pulse energy. When the two percentages (average power to rated power and pulse energy to
pulse handling capability) are added together, they must not exceed 100 % of the part’s overall rating.

dd the percentages in (4) and (6). If the percentage is less than 100 %, the resistor chosen is acceptable. If the
percentage is greater than 100 %, a resistor with a higher power rating or higher pulse handling capability should be
selected. Contact Vishay Dale engineering to determine the best resistor choice for your application.
Example
A series of equally spaced square wave pulses with an amplitude of 200 VDC, a pulse width of 20 ms, and a cycle time of
20 s, is applied to an RS007 100 Ω resistor at an ambient temperature of 25 °C.

3. The pulse energy is calculated: E = Pt = 400 W x 0.02 s = 8.0 W∙s, or J

5. The pulse handling capability (ER) provided by Vishay Dale engineering at an ambient temperature of 25 °C is 15.3 J
6. The percentage of pulse energy to pulse handling capability is calculated:

15.3 J
ER
7. The percentages calculated in (4) and (6) are added: 5.7 % + 52.3 % = 58 %
Since this percentage is less than 100 % of the overall rating, the RS007 style resistor will sufficiently handle the pulse.

WIREWOUND RESISTORS
Vishay Dale
Non-Inductive Resistors
Non-inductive power resistors consist of two windings, each of which is twice the finished resistance value. For this
reason, the energy capability will nearly always be greater than a standard wound unit. To calculate the energy capability
needed for non-inductive styles, compute the energy per ohm (J/Ω) by dividing the energy by four times the resistance
value.
Example
What is the energy per ohm pulse handling capability required to handle a 0.2 J pulse applied to a 500 Ω resistor?
The energy per ohm needed is:
0.2 J
E
=
= 100 x 10 -6 J/Ω
4R 4 x 500 Ω
This can be provided to Vishay Dale engineering in order to find the best product for the application.
Voltage Limitations
Short pulses – No overload voltage rating has ever been established for wirewound resistors when pulsed for short
durations. Sandia Corporation has performed a study on our NS and RS resistors using 20 µs pulses. This study indicates
that this type of unit will take about 20 kV per inch as long as the pulse handling capability is not exceeded.
Long pulses – For pulses between the cross-over point to 5 s, the recommended maximum overload is √10 times the
maximum working voltage for the 4 W size and larger, and √5 times the maximum working voltage for sizes smaller than 4 W.
Fusible Resistors
If the goal of the application is for the resistor to fuse open under a specific condition, Vishay Dale offers
fusible resistors. Reference page seven for common RS fuse resistor types, or click the following link for the entire
