What are the key features of 7077625?
- 270 Ω ±5% resistance in a standard 0.25 W axial through-hole package covers the majority of general-purpose current-limiting and pull-up resistor applications
- Carbon film construction provides low-noise performance compared to wire-wound alternatives, suitable for audio circuits and analog sensor interfaces
- Axial lead form factor with horizontal PCB mounting allows easy manual soldering and breadboard prototyping without specialized SMT equipment
- Temperature coefficient of -500 to +350 ppm/°C supports operation across a wide ambient temperature range for industrial and commercial environments
What is 7077625 used for?
The RS Pro 7077625 is suited for general-purpose current-limiting, biasing, and pull-up/pull-down resistor tasks in through-hole PCB prototypes, repair boards, and low-cost consumer electronic assemblies. Its 270 Ω, 0.25 W carbon film construction makes it appropriate for LED current-limiting circuits at 5 V and 12 V supply rails, signal conditioning in audio amplifiers, and input protection networks for analog sensors. The axial package facilitates rapid hand-soldering in laboratory setups and educational electronics projects where automated SMT processes are not available.

Frequently Asked Questions
At 5 V supply, how much current does the RS Pro 7077625 (270 Ω) limit through an LED in a simple series circuit?
With the 7077625 at 270 Ω in series with a standard red LED (forward voltage approximately 2.0 V) on a 5 V supply, the current is calculated as (5 V - 2.0 V) / 270 Ω ≈ 11.1 mA. This current falls within the typical 10 mA to 20 mA operating range of most standard LEDs, providing adequate brightness while keeping power dissipation across the resistor at approximately 33 mW, well within its 0.25 W rating.
How does the -500 to +350 ppm/°C TCR of the 7077625 affect its resistance over a 50°C temperature rise?
The temperature coefficient of -500 to +350 ppm/°C for the 7077625 means over a 50°C temperature increase, the resistance can shift by up to ±25 ppm/°C x 50°C = ±1.25%, or about ±3.4 Ω on the nominal 270 Ω value. For general-purpose applications such as LED current limiting and pull-up resistors, this variation is acceptable, though precision analog circuits requiring stable resistance should use metal film resistors with tighter TCR specifications of ±50 ppm/°C or better.
What is the maximum power this axial resistor can safely dissipate, and how does it affect circuit design choices?
The RS Pro 7077625 is rated at 0.25 W continuous power dissipation, which at 270 Ω corresponds to a maximum continuous current of approximately 30.4 mA or a maximum voltage of 8.22 V across the resistor. For 12 V supply circuits or high-current applications exceeding these limits, designers should select a 0.5 W or 1 W axial resistor of the same 270 Ω value to maintain adequate derating margin, typically operating at 50% of rated power for long-term reliability.
For which prototyping or repair scenarios is the 7077625 axial resistor more practical than an 0603 SMT resistor of the same value?
The 7077625 axial through-hole resistor is more practical than an 0603 SMT component in breadboard prototyping, through-hole PCB repair, and educational lab exercises where manual soldering without hot-air tools or microscopes is required. Its 2.5 mm to 25 mm adjustable lead spacing accommodates standard 2.54 mm pitch breadboards and perf boards, enabling quick circuit assembly and component swapping during debugging without the risk of losing the 1.6 mm x 0.8 mm SMT body.
