- 10 uH inductance with +/-5% tolerance, tested at 1 kHz
- 20 A maximum DC current
- 0.006 ohm DC resistance
- Minimum Q of 4.5
- Large ferrite core for extended saturation point; optimum range .01-2 MHz
- 1.5 in (+/- 0.1 in) leads, 14 gauge lead diameter
- Vinyl insulation shrink sleeve over coil
- Operating temperature -55 C to +135 C
The 1537E is a high current R.F. choke from the 1537 Series, specified at 10 uH with a tight +/-5% tolerance and a maximum DC current of 20 A. The part page describes it as an RF choke, heavy duty hash choke, suited to designers who need a leaded choke with a defined minimum Q.
The 1537E carries the highest current rating in the 1537 series at 20 A and the lowest inductance at 10 uH, with the heaviest leads in the range (14 gauge). Its nearest inductance neighbour in the series is the 1537F above it (20 uH, 12.5 A), so the 1537E fills the 10 uH step at 20 A.
Key electrical values for the 1537E: DC resistance of 0.006 ohms and a minimum Q of 4.5, with inductance tested at 1 kHz. The large ferrite core provides an extended saturation point, and the series lists an optimum frequency range of .01-2 MHz.
- Coil diameter: 0.63 in (16 mm)
- Core length: 1.25 in
- Leads: 1.5 in (+/- 0.1 in), 14 gauge lead diameter
- Operating temperature: -55 C to +135 C
The coil is covered with a vinyl insulation shrink sleeve. The part is RoHS and REACH compliant, ships at 0.05 lbs (0.02 kg), and carries UPC 623980298108 and UNSPSC 39121301.
Ideal For
- High current RF choke positions carrying up to 20 A DC
- Circuits operating in the .01-2 MHz optimum frequency range
- Designs needing 10 uH with +/-5% tolerance
- Equipment exposed to -55 C to +135 C operating temperatures
