Product Overview
Beyschlag MBA0204 series metal film resistors, 3.32 kOhm (3K32), 1% tolerance, 0.4W rated, axial lead through-hole configuration. Twenty pieces per lot. The MBA0204 is a professional thin-film leaded resistor in the compact 0204 body size - approximately 1.6mm diameter by 3.6mm length - with a ±50 ppm/K temperature coefficient. Long favored in European precision audio and industrial electronics for low current noise and stable resistance under thermal load.

Applications
- Replacing a drifted resistor in an analog audio signal path or feedback loop - desolder the failed part, bend the axial leads to match original pitch, drop in, solder, trim
- Restoring vintage European audio gear (amplifiers, preamps, mixing consoles) where Beyschlag metal film types were factory-fitted and low-noise performance matters
- Servicing legacy industrial control boards where a precise 3.32 kOhm value in a voltage reference or sensing line must be matched exactly to hold calibration
- Replacing out-of-spec resistors in vintage test equipment attenuator networks or bias circuits where the 0204 axial footprint must match the original PCB layout
- Precision voltage divider networks in DIY audio projects where 1% tolerance keeps channel balance tight
- Prototyping and breadboard builds where a small, precise metal film value in the 3K range is needed
Frequently Asked Questions
What is the physical body size, and will these fit my PCB?
The MBA0204 body is approximately 1.6mm in diameter and 3.6mm in length - the 0204 designation indicates a small body, notably more compact than a standard 1/4W 0207-size axial resistor. If your PCB was designed for 0207 or larger axial footprints, the body will fit the holes but the lead pitch may differ. Verify your PCB's hole spacing against the 0204 body dimensions before ordering.
Is 0.4W enough for my application, and how does it relate to the 1/8W designation?
The MBA0204 series is rated at 0.4W under current Vishay Beyschlag specifications. The 1/8W (0.125W) figure is a conservative historical rating associated with this body size from older catalog standards. In most signal-level and precision measurement circuits, actual dissipation is well below either figure. Calculate your circuit's actual power dissipation (V² / R or I² x R) and confirm it stays below 0.4W with appropriate derating for your thermal environment.
Are these compatible with lead-free (RoHS) soldering processes?
Not confirmed. Verify the specific lot's lead composition against your process requirements before use.
How many pieces are included?
Twenty pieces per lot.
A 3.32K metal film resistor is one of those values that sits in a lot of precision circuits without announcing itself - until it drifts, and suddenly nothing measures right. These are the exact replacements that put things back where they belong.
