Need CHR0805 1% 330kOhm resistors for electronics projects? Learn specs, sourcing tips, and practical applications with South African stock from Communica.
Easily source 330kOhm 1% SMD resistors from Communica's South African branches.
Comparison of tolerance, power, and footprint details for project compatibility.
Tips for students and professionals working with SMD components in SA labs.
CHR0805 1% 330kOhm resistors are surface mount (SMD) components used for precise voltage division, pull-up/pull-down networks, filtering, and current limiting in electronic circuits. The 0805 designation refers to the metric package size (2.0 mm x 1.25 mm), and the 1% tolerance means higher accuracy for sensitive applications. The "330kOhm" value is a common resistance for both analogue and digital circuitry, including op-amp input networks, sensor biasing, and signal-level interfacing.
| Spec | Typical Value | Notes |
|---|---|---|
| Footprint (0805) | 2.0 x 1.25 mm | Standard SMD format fits most PCBs and reflow setups |
| Resistance | 330,000 Ohm | Suitable for biasing, filters, and feedback networks |
| Tolerance | 1% | For applications needing precision-e.g., analogue, measurement |
| Power Rating | 0.125W (1/8W) typical | Check datasheet for specific make/model |
In circuits where tolerance impacts performance, such as voltage references, biasing, or signal integrity, using a 1% resistor like the CHR0805 type reduces drift and calculation errors. Projects involving sensor or ADC interfacing often demand these tighter tolerances.
Consider the following when specifying for your project:
If you apply 12 V across a 330kOhm resistor, the current is:
I = V/R = 12 V / 330,000 Ohm ~ 36 uA
Power = V x I = 12 V x 0.000036 A ~ 0.00043 W (0.43 mW)
This is well below the 0.125W rating, making the CHR0805 suitable for signal-level or pull-up tasks in most designs.
Communica stocks a broad range of SMD resistors, including the CHR0805 1% 330kOhm variant, in both retail and bulk options. Customers can search all products or filter by resistor category. Brands often available locally include Yageo, Royal Ohm, Panasonic, and other industry standards popular among SA hobbyists and engineers.
For urgent or recurring projects, local branch collection at the Samrand warehouse or Cape Town and Pretoria CBD branches can reduce project downtime. VAT invoices, student discounts, and account orders are also available-ideal for educational institutions and engineering departments.
