Construction
The resistance element is a precisely controlled thin film
of metal alloy on a high purity ceramic core, protected
by a cement coating applied so that terminations remain
completely clear.
This permits a well defined body length, (clean lead to
clean lead dimension L).
Terminations
Material
Solder-coated copper wire.
Strength
The terminations meet the
requirements of IEC 68.2.21
Solderability
The terminations meet the
requirements of IEC 115-1,
Clause 4.17.3.2

Marking
MF Series resistors are color coded with 4 or 5 bands depending
on value and tolerance. IEC colors are used.
Solvent Resistance
The body protection and marking are resistant to all normal
industrial cleaning solvents suitable for printed circuits.
Flammability
The resistors coating will not burn or emit incandescent particles
under any condition of applied temperature or power overload.

Application Notes
Packaging
1. If the resistors are to dissipate full rate power, it
is recommended that the terminations should not be
soldered closer than 4mm from the body.
MFP resistors are normally supplied tape packed ready for loading
onto automatic sequencing and insertion machines.
The standard taping method and critical dimensions are shown
below. Component wires will not protrude beyond the outside edge
of the tapes. All taped resistors will be supplied either on reels
or in ammopacks, depending on quantities ordered. Pre-formed
resistors are supplied loose packed in plastic bags or boxes. This
product and packaging is denoted code F.
2. Due to operating temperature limitations imposed
by some pcb materials, derating may be necessary. An
estimate of the temperature rise to be expected can be
calculated using the thermal impedance figures given
under Electrical Data.
3. MFP resistors can also be supplied pre-formed,
contact factory for details.

Value
(100 ohms and greater - First 3 significant figures plus 4th digit multiplier)
Example: 100 ohms = 1000, 1000 ohms = 1001, 150,000 ohms = 1503
(Less than 100 ohms - ‘R’ is used to designate decimal)
Example: 51 ohms = 51R0, 1 ohm = 1R00, 0.25 ohm = R250
Tolerance
F = 1%, G = 2%, J = 5%
