Axial-Leaded Resistors
High Energy Resistors - High Power Resistors
|
Download Axial-Leaded Datasheet (PDF) Ideal for replacement of Carbon Composition Resistors As alternatives to hard-to-find carbon composition resistors, Series 100 and 200 resistors can be used as drop-in replacements for 1 and 2 watt sizes. |
![]() |
|
Much larger sizes, up to 70 watts in a single component, are available for new or redesigns where an array of smaller resistors may have been previously required. |
|
Typical applications
- Soft start/In-rush limiters

1. Rated Power: De-rate linearly to 0 Watts at 230°C for Type AS. De-rate linearly to 0 Watts at 350 °C for Type SP.
2. Allowable peak energy/voltage will depend on the resistance value and pulse width. Energy ratings are based on pulse < 10 milliseconds. Type SP rating can be substantially greater for longer pulses. Consult Kanthal Globar.
3. Peak Current Ratings presume energy approaching rated peak energy values. Allowable current can be higher for lowe energy values. Consult Kanthal Globar.
4. Excludes caps/leads and coating.
