- Moisture and fungus resistant varnish with vinyl insulation covering
- Rated for -40°C to +105°C ambient; 1.5 in leads
The 1532B is an R.F. and hash choke from the 1531-1535 Series with 15 uH of inductance (+/- 10%) on an iron core and a maximum DC current of 1000 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 1532B delivers 15 uH on an iron core, rated for 1000 mA DC with a maximum DC resistance of 0.17 ohms and a 33 MHz minimum self-resonant frequency.
Electrically, the 1532B is specified with a minimum Q of 62 at a test frequency of 2.5 MHz, a self-resonant minimum frequency of 33 MHz and a maximum DC resistance of 0.17 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).
Ideal For
- RF choking on DC supply lines
- Hash noise suppression
- Circuits needing low distributed capacity windings
- Equipment operating from -40°C to +105°C ambient
