The 1812CS-333XJBC is a ceramic wirewound chip inductor manufactured by Coilcraft. This inductor is part of the 1812CS series and is designed for applications requiring a larger inductance value than the 0603 or 0805 series, while still maintaining good high-frequency performance.

Applications:

• RF circuits
• Wireless communication devices
• Mobile phones
• GPS devices
• Bluetooth modules
• Broadband communication
• Matching networks
• Filter circuits
• Oscillators

Features:

• 1812 package size (0.180" x 0.120")
• High Q factor
• High Self-Resonant Frequency (SRF)
• Tight tolerance inductance values
• Ceramic construction
• RoHS compliant

Benefits:

• Larger inductance values compared to smaller packages
• Improved circuit performance due to high Q and SRF
• Stable performance over a wide temperature range
• Reduced losses in high-frequency circuits
• Reliable performance

Additional Details:

The 1812CS-333XJBC has an inductance value of 33 µH with a specified tolerance. The Self-Resonant Frequency (SRF) is chosen to give optimal performance at higher frequencies. The Q factor allows for low losses. The operating temperature is typically -40°C to +125°C. Reflow soldering compatible, in tape and reel format for automated assembly.

Used in impedance matching, RF filters, and other high-frequency applications that need larger inductance and good performance. Ceramic construction enables stability and reliability even in harsh conditions.
