Pico Electronics, an approved QPL source, specializes in high quality, high reliability miniature power components. Their line of transformers includes: Audio, Interface, 400 Hz, Pulse, QPL, and DC-DC Converter Transformers.
Audio Transformers are manufactured to MIL-PRF-27 Grade 5 Class S. All catalog transformers are manufactured to meet Mil-Std-202, method 107, thermal shock from -55°C to +130°C. All units can be manufactured with a 300-thermal cycle guarantee. Audio Transformers can provide galvanic isolation, signal gain/loss, match impedances between two interfaces, can be used as a reference, and to provide feedback signal.
Pulse Transformers are manufactured to MIL-STD-1553 COMMAND/RESPONSE MULTIPLEX DATA BUS requirements, MIL-PRF-21038 specifications, and MAC AIR SPECIFICATIONS A3818, A5690, A5232, and A4905. Common mode rejection ratio is greater than 45dB at 1 MHz. Input impedance is greater than 3000 ohms over the band from 75 KHz to 1 MHz at 1 V rms. The Pulse Transformers possess exceptional waveform integrity – rise time and fall time is less than 100 nanoseconds. Overshoot and ringing is less than ±1V peak. Droop is less than 20%.
400 Hz miniature and ultra-miniature Power Transformers are manufactured to MIL-PRF—27, Grade 5, Class S and are available in both Surface Mount and Thru Hole packages.
Data Bus Pulse Transformers are designed and manufactured to meet MIL-STD-1553, MIL-PRF-21038, MAC air specifications A3818, A5690, A5232, and A4905. All catalog transformers are manufactured to meet MIL-STD-202, method 107, thermal shock from -55°C to +130°C. Units can be manufactured with a 300-thermal cycle guarantee. Common mode rejection ratio is greater than 45dB at 1MHz; Input impedance is greater than 3000 ohms over the band from 75kHz to 1MHz at 1V rms. Rise and fall times are less than 100 nanoseconds; overshoot and ringing is less than +/-1V peak; droop is less than 20%. Standard as well as custom designs are available.
Another series of Pulse Transformers, the 682xx and 683xx, are designed to meet QPL MIL – PRF – 21038/27 standards, and are in strict compliance to MIL – PRF – 21038. Pico is the supplier for MIL-PRF-21038/27 -01 thru -31 parts. High input impedance ranges from 75 kHz to 1 MHz, with temperatures of -55°C to +130°C, maximum 20% droop, and overshoot of 1V maximum. Common mode rejection (CMR) is greater than 45dB. Units can withstand 100Vrms from primary to secondary, are epoxy encapsulated, and achieve MSL of 3. Pico Electronics is qualified to test these transformers to level M and level T.
Pico’s DC–DC Converter Transformers are used in step-up or step-down converters, in self-saturated or square wave driven applications. Input voltages are 5V, 12V, 24V, and 48V; output Voltages extend up to 300 VDC, with power ratings to 7.5 W for surface mount. The power ratings for thru-hole transformers go up to 40W and these transformers are magnetically shielded. The DC-DC Converter Transformers operate in temperatures of -55°C to +105°C and are MIL-PRF-27 Grade 5 Class S.
Their Inductor line includes EMI, Miniaturized Power, Power, Hi Q, and High Current EMI. EMI Common Mode Suppression Inductors are used for noise filtering, spike, and output filtering applications in Switching Regulators, AC-DC Power Supplies, DC-DC Power Supplies, and other electrical equipment to minimize interference with other equipment operating on the same power line. These Inductors are manufactured to Mil-PRF-27, Grade 5, Class S.
