AE475TCB Series
Current Sense Transformers
AE475TCB Series designed for use up to 1 MHz and above to sense continuous currents to 7 Amps.
- Miniature SMT design, only 4.5 × 4.8 mm footprint.
- 500 Vrms, one minute isolation (hipot) between windings.
- Passes NASA low outgassing (Outgassing meets ASTM E595).
- Tin-lead (63/37) over tin over nickel over copper terminations.

Notes
- When ordering, please specify termination and screening codes: e.g. AE475TCB1150SZ.
- Inductance measured between secondary pins at 100 kHz, 0.1 Vrms, 0 Adc.
- Primary current of 7 A causes less than 25°C temperature rise from 25°C ambient. Higher current causes a greater temperature rise (see Temperature Rise vs Current curve).
- Volt-time product is for the secondary, between pin 1 and 2.
- For specific questions regarding frequency range, please contact us at [email protected].
- Terminating resistance (RT) value is based on 1 Volt output with 20 Amps flowing through the primary. Varying terminating resistance increases or decreases output Voltage/Ampere according to the following equation: RT = Vout × Nsec/Iin.
Termination:
- S = Tin-lead (63/37) over tin over nickel over copper
- T = Tin-silver-copper (95.5/4/0.5) over tin over nickel over copper
- L = Tin-silver (96.5/3.5) over tin over nickel over copper
Screening:
- Z = Unscreened
- H = Group A screening per Coilcraft CP-SA-10001
- F = ESCC3201 (F4 operational life performed at 90°C)
- 1 = EEE-INST-002 (Family 1) Level 1
- 2 = EEE-INST-002 (Family 1) Level 2
- 3 = EEE-INST-002 (Family 1) Level 3
- 4 = MIL-STD-981 (Family 11) Class B
- 5 = MIL-STD-981 (Family 11) Class S
- Screening performed to the document’s latest revision.
- Lot qualification (Group B) available.
- Custom testing also available.
