High power axial-leaded resistors

Non-inductive, high voltage, high-energy, high power axial-leaded resistors providing excellent performance that must be handled in a small size.

As alternatives to hard-to-find carbon composition resistors, Globar® non-inductive high power axial-leaded 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 re-designs where an array of smaller resistors have been previously required.

1) Rated power: De-rate linearly to 0 Watts at 230°C for Type AS and BA. 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 us if you need more information.
3) Peak Current Ratings presume energy approaching rated peak energy values. Allowable current can be higher for low energy values. Consult us if you need more information.
4) Excludes caps/leads and coating.
