Resistor 0.5W 680K ohm (5 pcs)

The Resistor 0.5W 680K ohm is a through-hole fixed resistor with a resistance of 680 kΩ and a power rating of 0.5 W, sold in a pack of 5. Very high values like 680 kΩ draw almost no current, so they are used in high-impedance voltage dividers, bias networks, long RC time constants and bleeder resistors across capacitors.

Resistor 0.5W 680K ohm Specifications

• Resistance: 680 kΩ (680,000 ohms)
• Power rating: 0.5 W (1/2 W)
• Type: fixed resistor, axial leads, through-hole

Resistor 0.5W 680K ohm Applications

• Low-drain battery voltage dividers for microcontroller inputs
• Long timing intervals with 555 timers and RC circuits
• Biasing high-impedance op-amp and FET inputs
• Bleeder resistors across filter capacitors
• High-value pull-down resistors on CMOS inputs

What's in the Box

• 5 × 680 kΩ 0.5 W resistors

Tip: Resistors have no polarity, so they can be fitted either way round. At 5 V a 680 kΩ resistor passes only about 7 µA. Very high values pick up noise more easily, so keep leads short and add a small capacitor, such as 100 nF, at the ADC pin when reading a high-value divider.

Orders placed before 14:00 are ready for pickup the same day. Delivery across Lebanon usually takes 1–3 working days.
