OA Series

OPEN FRAME LOW INDUCTANCE  AXIAL TYPE 1 W TO 3 W R 003 TO R 10

Physical configuration
 

HTR TYPE POWER RATING at 70°C DIMENSIONS (mm) RESISTANCE RANGE  L1 MIN MAX OA-1 1W 11mm TO 15mm R003 R051 OA-2 2W 16.3mm TO 21mm R0041 R068 OA-3 3W 28mm TO 33mm R0056 R10

NOTE:
Resistance values must be checked using 4 ½ digit micro ohm meter with four wire system and insulated clips, which should be attached to the resistor leads 10mm from the weld point.

TYPICAL APPLICATIONS:
The OA series offers a non insulated, non-inductive resistor having high stability / overload capacity.The solder plated copper terminals are spot welded to the alloy resistive element forming a very reliable all welded construction, which is finding increasing usage in switching and linear power supplies, instruments, regulators and other modern current sensing circuits.

MARKING:
Due to the nature of their construction, these resistors cannot be marked however, the resistance value & other relevent details will be on the packing box.
