The MFR25F 100KOhm metal film resistor is a popular value for analog circuits, microcontroller pull-ups, and signal conditioning. The "MFR25F" series, frequently supplied by brands like UniOhm, Yageo, and Royal Ohm, offers 0.25W power rating, tight tolerance, and reliable long-term stability. For South African buyers, checking up-to-date pricing and branch availability ensures your project timelines stay on track.
| Parameter | MFR25F 100K Standard |
|---|---|
| Resistance | 100,000 Ohm (100K) |
| Power Rating | 0.25W (1/4W) |
| Tolerance | 1% or 5% |
| Technology | Metal Film (Axial Leaded) |
| Typical Brands | UniOhm, Yageo, Royal Ohm |
These resistors are suitable for education, hobby, and industrial applications. The 100KOhm value works well for timing, biasing circuits, and as pull-ups in digital designs.
Pricing for MFR25F 100K resistors in South Africa typically ranges as follows (as of Q2 2024):
| Quantity | Estimated Price (ZAR/unit) |
|---|---|
| 1-9 | R0.90 - R1.20 |
| 10-99 | R0.60 - R0.90 |
| 100+ | R0.35 - R0.60 |
| 1000+ | Enquire for bulk pricing |
Communica maintains significant stocks of common E24 and E12 range resistors, including MFR25F 100KOhm, at their Samrand (Centurion), Pretoria CBD, and Cape Town branches. Online inventory lets you check up-to-date availability and approximate lead times. During periods of global supply constraint, popular values like 100KOhm are prioritized for branch stock, but it is advisable to confirm quantities for large runs or institutional orders.
When selecting 100KOhm metal film resistors, consider key factors beyond price and basic value:
Suppose you use a 100K resistor as a pull-up on a 5V logic input:
| V (supply) | 5V |
| R (resistor value) | 100,000Ohm |
| Current (I=V/R) | 0.00005A (50A) |
| Power (P=VI) | 0.00025W (well below 0.25W rating) |
This shows one reason the 100K 1/4W metal film is a widespread choice for low-power bias and signal conditioning across student, hobbyist, and light industrial projects.
Browse all resistor types or filter by preferred brand for project consistency and datasheet matching.
