0805J1000331MCTE03

Overview

The Knowles Syfer 0805J1000331MCTE03 is a multilayer ceramic capacitor (MLCC) designed for surface mount technology. It features a capacitance of 330 pF with a tolerance of ±20%. The component operates at a DC voltage rating of 100 V and utilizes C0G (NP0) dielectric material, ensuring stable performance across varying conditions. It is housed in an 0805 (2012 metric) package with dimensions of 2.00 mm x 1.25 mm x 1.30 mm. The device supports a temperature range from -55°C to +125°C and offers termination options including standard SMD/SMT or X2Y configurations with nickel barrier and 100% tin plating.

Procurement Notes

Verify the specific termination configuration required for your design, as this part number may correspond to either standard MLCC or X2Y variants depending on the full suffix. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement. Ensure that the selected packaging format matches your assembly line capabilities. Cross-reference the exact datasheet version to confirm dimensional tolerances and electrical specifications align with your circuit requirements.

Selection Notes

Select this component when a stable C0G dielectric is necessary for precision timing or RF applications. The 0805 footprint allows for moderate current handling and thermal dissipation compared to smaller packages. Consider the X2Y variant if integrated common-mode noise suppression is required without additional discrete components. Evaluate the operating temperature range to ensure compatibility with the environmental conditions of the target application.

Part Context

This component belongs to the Knowles Syfer general type MLCC series, specifically within the 0805 case size family. It represents a standard passive component used widely in consumer, industrial, and automotive electronics. The J code indicates a 100V DC voltage rating, while the 331 code denotes the 330 pF capacitance value. This series is known for its consistency in manufacturing quality and adherence to strict automotive qualification standards where applicable.

Replacement Considerations

Direct substitutes include other 0805 C0G capacitors with identical 330 pF and 100V ratings. Verify terminal plating and dielectric stability class to ensure functional equivalence. For X2Y functionality, specific replacement models must maintain the three-terminal architecture.
