Resistor 0.5W 75 ohm (5 pcs)

The Resistor 0.5W 75 ohm is a through-hole fixed resistor with a resistance of 75 Ω and a power rating of 0.5 W, sold in a pack of 5. 75 Ω matches the characteristic impedance of standard video and TV coaxial cable, so it is the usual value for terminating composite video lines. It is also useful for current limiting in 3.3 V and 5 V LED and transistor circuits.

Resistor 0.5W 75 ohm Specifications

• Resistance: 75 Ω

• Maximum current: about 80 mA at the full 0.5 W rating
• Colour code: violet, green, black (4-band) or violet, green, black, gold (5-band), plus a tolerance band
• Type: fixed resistor, axial leads, through-hole
• Pack size: 5 pieces

Resistor 0.5W 75 ohm Applications

• Terminating 75 Ω composite video and coaxial lines
• Current limiting for LEDs on 3.3 V supplies
• Series resistors in transistor and MOSFET drive circuits
• Small loads and dividers in low-voltage circuits
• Electronics education and repair work

What's in the Box

• 5 × 75 Ω 0.5 W resistors

Tip: From a 3.3 V supply, a 75 Ω resistor with a red LED (about 2 V) gives roughly 17 mA. Do not use it with blue or white LEDs on 5 V without checking: the current would be close to 27 mA, above the usual 20 mA limit.
