The 14 watt 1k ohm carbon film resistor 5 tolerances 025w 200pcs 4 is a compact through-hole component built for general-purpose voltage division, current limiting, and feedback networks. With a 14 watt pulse and steady-state capacity, 1k ohm nominal resistance, and five available tolerance grades, these resistors suit both hobbyist prototyping and basic industrial boards.
Designed in 025 watt axial packages and sold in 200 piece kits, these carbon film resistors balance cost, availability, and stable performance across temperature cycles. Engineers often choose this combination when they need reliable 1k ohm values in a space-efficient, standardized footprint.

Key Electrical Specifications
Resistance and Power Ratings
The 14 watt rating supports short surge handling while the 025w continuous rating keeps board temperatures low. The 1k ohm carbon film resistor delivers stable resistance under typical circuit conditions.
Tolerance and Stability
Five tolerance bands allow designers to match precision needs to system requirements. Carbon film layers provide predictable behavior over time, maintaining calibration in most environments.
Physical and Packaging Details
Axial Lead Style
The axial design simplifies manual insertion and automated placement. Standard 025w packaging fits common strip boards and prototype arrays without special sockets.
Kit Quantity and Storage
Supplied as 200 pieces per box, these resistors work well for bulk replacement, repair stations, and production lines. Keep sealed bags in dry, low-humidity storage to preserve lead integrity and film uniformity.
Performance in Common Circuits
Voltage Divider and Biasing
When paired with matching values, the 1k ohm resistor maintains ratio accuracy across moderate temperatures. Designers can stack different tolerance grades to fine-tune divider error budgets.
LED Current Control
Using a 14 watt resistor in high-current LED strings adds thermal headroom. The 1k ohm value sets drive levels where system voltage and forward drops require wider margins.
Selection and Integration Recommendations
- Match tolerance grades to circuit error budgets to avoid over-spec’ing cost
- Check derating curves for sustained loads near 0.25 W
- Verify lead diameter and hole spacing for your PCB tooling
- Store in controlled humidity to preserve carbon film stability
- Use consistent values from the same batch for divider networks
FAQ
Reader questions
Can I use these resistors in a power supply feedback loop?
Yes, the 1k ohm carbon film resistor with 5 tolerances works in feedback paths where power dissipation stays within 0.25 W and surge loads remain under 14 W.
Are 200 pieces per box enough for a small production batch? For small batches and prototype runs, 200 pieces typically cover multiple panel builds with spares for testing and rework. How do I read the color bands for 1k ohm ±5% on this 025w package?
Brown, black, red, gold indicates 1k ohm with ±5% tolerance, and the small body confirms the 025w axial package.
Will these resistors work in automotive environments?
They suit non-critical automotive circuits; verify temperature and vibration limits before deploying in under-hood applications where cyclic stress is high.
