Resistor 0.25W 1.3 ohm (10 pcs)

The Resistor 0.25W 1.3 ohm is a through-hole fixed resistor with a resistance of 1.3 Ω and a power rating of 0.25 W, supplied in a pack of 10. It is a low E24 value used for current sensing, emitter resistors and replacing worn parts in circuits that specify 1.3 Ω.

Resistor 0.25W 1.3 ohm Specifications

• Resistance: 1.3 Ω, a standard E24 value
• Power rating: 0.25 W (1/4 W)
• Maximum current at full power: about 439 mA
• Voltage drop: 0.13 V for every 100 mA flowing through it
• Type: fixed resistor, axial leads, through-hole
• Fits: breadboards, perfboards and PCBs
• Pack size: 10 pieces

Resistor 0.25W 1.3 ohm Applications

• Shunt resistors for measuring current with an analog input or op-amp
• Stabilising transistor amplifier and driver stages
• Low-value series resistance in low-voltage power and signal lines
• Replacement part for repairs that call for 1.3 Ω at 1/4 W
• Electronics teaching and Ohm's law experiments

What's in the Box

• 10 × 1.3 Ω 0.25 W resistors

Tip: At 300 mA a 1.3 Ω resistor dissipates about 0.12 W, well within its rating. Above about 439 mA it would exceed 0.25 W, so choose a higher-wattage resistor for larger currents.
