Description

The Resistor 0.25W 7.5 ohm is a quarter-watt through-hole resistor with a low resistance of 7.5 Ω, supplied in a pack of 10. It is an E24 value used for current sensing, MOSFET gate resistors and other spots where a small, precise resistance is needed without a large voltage drop.

Resistor 0.25W 7.5 ohm Specifications

  • Resistance: 7.5 Ω (7.5 ohms)
  • Power rating: 0.25 W (1/4 W)
  • Value series: standard E24 value
  • Colour code: violet, green, gold (4-band) or violet, green, black, silver (5-band), followed by the tolerance band
  • Maximum current: about 183 mA at the full 0.25 W
  • Maximum voltage: about 1.37 V across the resistor at the full 0.25 W
  • Type: fixed resistor, axial leads, through-hole
  • Pack size: 10 pieces

Resistor 0.25W 7.5 ohm Applications

  • Current-sense resistors for loads up to about 100 mA
  • Gate resistors for power MOSFETs with a gate-driver IC
  • Series resistors to limit current into small speakers
  • Making other low values: two in parallel give 3.75 Ω
  • Electronics education and prototyping

What's in the Box

  • 10 × 7.5 Ω 0.25 W resistors

Tip: An LM317 with 7.5 Ω sets about 167 mA, but the resistor would dissipate about 0.21 W, close to its limit. For that job use two 15 Ω resistors in parallel, which gives the same 7.5 Ω with the heat shared between them.
