Engineered for high-noise power systems, the TPER Series delivers industry-leading EMI suppression with 39A rated current and 1500V isolation. Featuring ER19/ER25 planar cores, it achieves ultra-low DCR (down to 1.4mΩ) and precision SRF control (0.95–2.0MHz). Shielded SMT construction minimizes crosstalk, while RoHS/EIA481 compliance ensures automated assembly readiness. Optimized for synergy with EMC filters in electric vehicle chargers and industrial inverters.

Performance
Operating Temp: –40℃ to +150℃ (TPER25)
Current Rating: Based on 50℃ temp rise (free air cooling)
Tape/Reel: EIA481 compliant
*Rated current = RMS current causing 50℃ temperature rise
Applications
Electric Vehicles
DC-DC converters (39A current support for battery systems)
On-board chargers (1.42MHz SRF targets CISPR 25 EMI bands)
Industrial Power
Solar inverters (1500V isolation for 1.2kV bus systems)
Motor drives (1.4mΩ DCR minimizes power loss)
Data/Telecom
Server PSUs (2.0MHz SRF suppresses switch-mode noise)
5G power modules (Planar profile fits high-density PCBs)
Consumer Electronics
USB-PD 3.1 adapters (1.42MHz peak impedance for 140W designs)
LED drivers (RoHS-compliant for global markets)
Q: How does planar choke outperform toroidal cores?
A: 30% lower profile (18mm vs 25mm), 50% faster assembly (SMT vs through-hole), and tighter SRF control (±5% vs ±20%).
Q: Can it replace power inductors in DC-DC circuits?
A: No. Designed for EMI suppression (not energy storage). Pair with power inductors for full EMC compliance.
Q: Is thermal derating required at high ambient temps?
A: Yes. Max current = Rated current × [(150 – Ambient Temp)/50]. E.g.: 39A @25℃ → 23.4A @120℃.
Q: Custom impedance curves supported?
A: Yes. Contact for SRF tuning (e.g., 1.0MHz±3% for medical devices).
