STPTIC-82G2C4

Overview

The STPTIC-82G2C4 is an RF analog tunable capacitor from STMicroelectronics, part of the Parascan™ family. It operates within a frequency range of 700MHz to 2.7GHz, supporting GSM, LTE, and WCDMA standards. The device features a capacitance range of 1.53 pF to 10.86 pF and is housed in a compact 3-WLCSP package measuring 0.75x0.72 mm.

Feature Summary

• Offers high linearity and low power consumption for adaptive RF applications
• Provides a 5:1 tuning range with high quality factor (Q)
• Features high power capability and low leakage characteristics

Applications

• GSM cellular modules
• LTE wireless communication devices
• WCDMA mobile phone front-ends

Procurement Notes

Verify the specific suffix G2C4 against official STMicroelectronics documentation to confirm pinout and electrical specifications. Ensure compatibility with surface mount assembly processes suitable for WLCSP packages. Confirm RoHS compliance status through current manufacturer declarations rather than distributor listings.

Selection Notes

Select this component when designing RF front-ends requiring integrated tunability for multiple cellular bands. The small 3-WLCSP footprint is ideal for space-constrained mobile devices. Evaluate the 1.53 pF to 10.86 pF range against circuit requirements for impedance matching networks operating between 700MHz and 2.7GHz.

Part Context

This device belongs to STMicroelectronics' Parascan™ tunable capacitor series, designed to replace fixed capacitor arrays in modern wireless terminals. It integrates varactor technology into a miniature form factor, enabling dynamic impedance matching without mechanical components or complex switching networks.

Replacement Considerations

Cross-reference with other Parascan™ variants such as STPTIC-82C4 for similar performance profiles. Verify package dimensions and electrical parameters before substitution to ensure board layout compatibility and signal integrity in existing designs.
