Overview
The SMV1130-040LF is a hyperabrupt junction tuning varactor diode manufactured by Skyworks Solutions, Inc. It is housed in an SOD-882 surface-mount package with a series inductance of 0.45 nH. The device features a maximum reverse voltage of 26 V and a power dissipation rating of 250 mW. At a reverse voltage of 1 V and frequency of 1 MHz, the typical capacitance is 21.2 pF, with a minimum capacitance ratio of 1.47 at 1 V to 3 V. The series resistance is typically 0.8 Ω at 500 MHz. Operating temperature ranges from -55 °C to +125 °C.
Feature Summary
- Designed for high-volume, low-cost systems requiring wideband Voltage-Controlled Oscillator (VCO) applications.
- Optimized for very high capacitance tuning ratios combined with low series resistance.
- Packages are rated for Moisture Sensitivity Level 1 (MSL1) and withstand soldering temperatures up to 260 °C per JEDEC J-STD-020.
Applications
- Wideband Voltage-Controlled Oscillators (VCOs)
- High-volume, low-cost wireless systems
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via the official Skyworks Certificate of Conformance. Ensure storage conditions adhere to moisture sensitivity guidelines to prevent damage during lead-free solder assembly processes.
Selection Notes
Select the SMV1130-040LF when an SOD-882 footprint is required, as opposed to the SC-79 package used by the SMV1130-079LF variant. Consider the specific series inductance of 0.45 nH for circuit matching. Evaluate the breakdown voltage of 26 V against system peak reverse voltage requirements.
Part Context
This component belongs to the SMV1130 series of hyperabrupt junction tuning varactors. The series includes the SMV1130-079LF, which utilizes an SC-79 package and exhibits a higher series inductance of 0.70 nH compared to the 0.45 nH found in the SMV1130-040LF model.
Replacement Considerations
The SMV1130-079LF serves as a functional alternative within the same series, distinguished primarily by its SC-79 packaging and 0.70 nH series inductance. Designers must account for the physical footprint differences and inductance variations when substituting this part.
FAQ
What is the typical capacitance value of the SMV1130-040LF at 1 V?
