- 5H inductance (+/- 15%) at 50 ma. rated D.C. current
- 270 ohm D.C. resistance (+/- 15%)
- 400 V DC maximum operating voltage
- Economical open bracket channel mount, C4H mounting style
- Every unit Hipot tested (100%) at 1,500 VAC
- Vacuum impregnated with polyurethane varnish for quiet operation and long life
- Minimum 5" long leads
- RoHS and REACH compliant
Rated 5H at 50 ma., the 155H is an open-bracket filter choke (D.C. reactor) in the 153-159 Series for low to medium current circuits. OEM designers, repair technicians and builders of high voltage power supplies use chokes of this type for supply filtering. The 155H is rated 5H at 50 ma. with 270 ohms of resistance and a 400 V DC maximum, for supplies a step above the 300 V rating of the 153 and 154 sizes.
The DC resistance is 270 ohms and the unit is rated for 400 V DC maximum operation, with tolerances of 15% on inductance and resistance. Inductance values are taken at the rated D.C. current and will fall slightly above it and rise below it.
The choke is built on an open bracket channel frame and vacuum impregnated with polyurethane varnish for quiet, long-life operation. Each unit is 100% Hipot tested at 1,500 VAC and supplied with leads at least 5" long.
Its drawing gives dimensions A 2.38" (60.5 mm), B 1.38" (35.1 mm), C 1.38" (35.1 mm) and D 2" (50.8 mm), with a weight of 0.3 lbs / 0.14 kg. The part page lists a shipping weight of 0.3 lbs (0.14 kg), and the 155H is RoHS and REACH compliant (UNSPSC 39121301, UPC 623980202006).
Ideal For
- 50 mA high voltage power supply filtering

Frequently Asked Questions
What are the inductance and current ratings of the 155H?▾
The 155H is rated 5H (+/- 15%) at 50 ma. D.C. current, with 270 ohms (+/- 15%) of resistance.
What is the maximum operating voltage of the 155H?▾
The 155H is rated for 400 V DC maximum operating voltage.
Will the 155H hold its inductance at a different current?▾
Inductance is measured at the rated 50 ma.. The series data notes units exhibit less inductance at slightly higher currents and more inductance at lower currents.
How does the 155H mount and how big is it?▾
It uses an economical open bracket channel mount (mounting style C4H). Its drawing gives dimensions A 2.38" (60.5 mm), B 1.38" (35.1 mm), C 1.38" (35.1 mm) and D 2" (50.8 mm), with a weight of 0.3 lbs / 0.14 kg.
Is the 155H RoHS and REACH compliant?▾
Yes. The part page lists the 155H as both RoHS compliant and REACH compliant.
Is every 155H tested?▾
Yes. Every unit in the series is Hipot tested (100%) at 1,500 VAC, and units are vacuum impregnated with polyurethane varnish.
