Product Description

Our new generation of planar power inductors utilize precision-wound flat copper coils and advanced ferrite cores to deliver an industry-leading 39A continuous current within a compact ER25 package size (30.5x27mm). Featuring 1500V enhanced isolation, they meet the demands of critical medical and automotive applications.

Precision Noise Suppression at 1.6MHz SRF

Switch-mode power supplies above 500kHz face vicious EMI spikes near the self-resonant frequency (SRF). Unlike conventional toroidal RF inductors, our planar architecture achieves controlled SRF at 1.6MHz (TPER25-161Y model) with impedance peaks of 400Ω – 2× higher than industry averages. This translates to:

30% lower conducted emissions in 65W USB-PD adapters (per CISPR 32 tests)
Elimination of re-spins caused by 1-2MHz band failures in GaN-based designs
Compatibility with high-speed EMI Filter stages near IC drivers

1500V Reinforced Isolation: Safety by Design

Medical and automotive systems demand fail-safe isolation. Our 1500V reinforced isolation choke exceeds IEC 60601-1 and ISO 6469-3 requirements through:

Triple-insulated windings with >8.0mm creepage/clearance
100% production HIPOT testing at 1500VAC/60s (zero leakage)
-40°C to +150°C operational stability for engine bay environments

Application	Challenge	Our Solution	Key Result
EV On-Board Chargers	800V battery isolation requirements	1500V reinforced isolation choke	Passed ISO 7637-2 pulses 5a/5b
Server PSUs	12V/100A VRM ripple control	1.6MHz SRF EMI filter choke	<10mVpp noise at full load
Industrial IoT	Space-constrained Sensor power	ER25 planar inductor (30x27mm)	50% smaller vs. conventional
