Hammond 1532D 39 uH Iron-Core RF Hash Choke, 600 mA

The 1532D is an R.F. and hash choke from the 1531-1535 Series with 39 uH of inductance (+/- 10%) on an iron core and a maximum DC current of 600 mA. It is aimed at designers and repair technicians who need a single-layer solenoid choke to block RF or suppress hash noise on a DC or signal line.

The 1532D offers 39 uH on an iron core, rated for 600 mA DC with 0.65 ohm maximum DC resistance and a minimum Q of 70. The manufacturer's table lists its self-resonant minimum frequency as 0.2 MHz.

Electrically, the 1532D is specified with a minimum Q of 70 at a test frequency of 2.5 MHz, a self-resonant minimum frequency of 0.2 MHz and a maximum DC resistance of 0.65 ohms. The coil is wound as a solenoid (single coil) winding, which the series uses to keep distributed capacity low.

The coil diameter is 0.29 in (7 mm) and the core length is 0.88 in (22 mm). Series-wide, all models are impregnated with a moisture and fungus resistant varnish, include a vinyl insulation covering, have a lead length of 1.5 in (+/- 0.13 in) and are rated for an ambient temperature range of -40°C to +105°C.

The part is listed as RoHS and REACH compliant, and ships at 0.05 lbs (0.02 kg).
