DV-704A Series HIGH RELIABILITY HYBRID EMI FILTERS DESCRIPTION FEATURES The DV-704A is a combined hybrid EMI filter and voltage spike protection module that is operable over the full military (-55 °C to +125 °C) temperature range with no power derating. The DV-704A EMI filter is designed to be used with VPT/Delta’s DVSA, DVHF, DVTR, and DVFL series DC-DC converters to comply with the surge requirements of MIL-STD704A, B, C, and D with 40 watts maximum output power. This device also reduces the reflected noise of the DC-DC converters to meet MIL-STD-461C CE03 and MIL-STD-461D CE102 limits. It also protects the DC-DC converters against the voltage spikes specified in MIL-STD-461C CS06 and conducted susceptibility in MIL-STD-461C CS01 and CS02. • • • • • • • • These filters are designed and manufactured in a facility qualified to ISO9001 and certified to MILPRF-38534 and MIL-STD-883. This product may incorporate one or more of the following U.S. patents: • • • • • • High Reliability Up to 2.0 Amps Maximum Current 40 dB Minimum Attenuation at 500 kHz Industry Standard Pinout Inrush Current Limit and Soft Start Under Voltage Lockout Clamps Output Voltage to 50 Volts Maximum Precision Seam Welded or Solder Seal Hermetic Package Custom Versions Available Additional Environmental Screening Available Meets MIL-STD-704A, B, C, and D Surge Limits Compliant to MIL-STD-461C CE03 and MILSTD-461D CE102 EMC Requirements Protects Against Conducted Susceptibility Specified in MIL-STD-461C, CS01 and CS02 and Against Voltage Spikes Specified in MILSTD-461C CS06 MIL-PRF-38534 Element Evaluated Components 5,784,266 5,790,389 5,963,438 5,999,433 6,005,780 6,084,792 6,118,673 Figure 1 – DV-704A EMI Filter (Not To Scale) 1X019DSD 11314 4th Avenue West, Suite 206 Everett, WA 98204 http://www.vpt-inc.com Sales Information: Phone: (425) 353-3010 Fax: (425) 353-4030 E-mail: [email protected] 1 DV-704A Series SPECIFICATIONS (TCASE = -55°C to +125°C, VIN = +28V ± 5%, Full Load, Unless Otherwise Specified) ABSOLUTE MAXIMUM RATINGS Input Voltage (Continuous) Input Voltage (Transient, up to 20µs) Output Current3 Weight (Maximum) 40 VDC 600 Volts 2.0 Amps 47 grams Parameter Power Dissipation (Continuous) Power Dissipation (Peak) Storage Temperature Lead Solder Temperature (10 seconds) 15 Watts 500 Watts -65°C to +150°C 300°C DV-704A Conditions Min Typ Units Max STATIC INPUT 2 Voltage Current Continuous No Load 0 28 40 V Continuous 2.0 A Load 15 28 40 V Transient 100 ms, RS = 0.0 Ω - - 80 V Transient 60 ms, RS = 0.5 Ω - - 100 V Transient 20 µs, RS = 50 Ω - - 600 V 1 OUTPUT Voltage Current No Load - - 10 mA Inhibited - - 2.0 mA Continuous 3,4 INHIBIT PIN VOLTAGE 2 2 VOUT = VIN – (IIN x RDC) V Continuous 0 - 2.0 Open Circuit - 14 16 A V Inhibited 0 - 0.8 V - - -300 µA UNDERVOLTAGE LOCKOUT 7.0 - 14 V OUTPUT CLAMP VOLTAGE 43 - 47 V 2.0 A Load, 80 V - - 100 ms 2.0 A Load, 100 V - - 80 ms 2.0 A Load, 600 V, RS = 50 Ω - - 20 µs 2.0 A Load, 400 V, RS = 0.5 Ω - - 20 µs VIN = 0 – 28V, No Load CL = 100µF - 0.25 0.5 APK Continuous - - 450 mΩ Continuous - - 15 W Peak - - 500 W f = 500 kHz 50 - - dB Pin to Case - 20 - nF 100 - - MΩ - 0.627 - MHrs INHIBIT PIN CURRENT INPUT SURGE LIMIT Inhibit Pin Voltage = 0 to 0.8 V 2 2 INPUT SPIKE LIMIT INPUT INRUSH CURRENT DC RESISTANCE POWER DISSIPATION NOISE REJECTION CAPACITANCE 2 2 ISOLATION Any Pin to Case, 500 VDC MTBF (MIL-HDBK-217F) AIF @ TC = 55°C Notes: 1.
