Overview
The Knowles Syfer 0805J0500390MCTE07 is a surface-mount multilayer ceramic capacitor (MLCC) in an 0805 (2012 metric) package. It features a C0G (NP0) dielectric with a capacitance of 39 pF and a tolerance of ±20%. The component has a DC voltage rating of 50 VDC and utilizes nickel barrier end terminations with 100% tin plating. It operates within a temperature range of -55°C to +125°C.
Feature Summary
- Utilizes C0G (NP0) dielectric for stable capacitance characteristics across varying temperatures and voltages.
- Features nickel barrier end termination technology compatible with standard reflow soldering processes.
- Designed for high-frequency applications requiring low loss and precise capacitance stability.
Applications
- High-frequency RF circuits
- Oscillator tuning networks
- Impedance matching networks
Procurement Notes
Verify the specific suffix 'TE07' against official manufacturer documentation to confirm reel packaging specifications and tape dimensions. Ensure the part number matches the exact tolerance code 'M' (±20%) and voltage rating '050' (50V). Cross-reference with the latest datasheet to confirm availability status and any recent design changes or obsolescence notices from Knowles Syfer.
Selection Notes
Select this component when a small capacitance value with wide tolerance is required for high-frequency stability. The C0G dielectric ensures minimal capacitance change with temperature and voltage. The 0805 package offers a balance between size and power handling. Verify that the ±20% tolerance meets the circuit requirements, as tighter tolerances are available in other variants.
Part Context
This part belongs to the Knowles Syfer general-purpose MLCC line. The '0805' prefix indicates the case size. The 'J' denotes the 50V voltage rating. The '0390' specifies the 39 pF capacitance value. The 'M' indicates the ±20% tolerance. The 'C' typically refers to the C0G/NP0 dielectric. The 'TE07' suffix usually denotes tape-and-reel packaging.
Replacement Considerations
Publicly confirmed substitute part numbers for this specific variant are not available in the provided source data. Users should consult the manufacturer's catalog for direct replacements or parameter-equivalent components with similar voltage, capacitance, and tolerance ratings.
