3-16-1DL

Overview

The Bourns Inc. 3-16-1DL is a balanced-to-unbalanced transformer (balun) designed for RF and wireless applications. It operates within a frequency range of 300 kHz to 120 MHz and provides a 1:16 impedance transformation ratio. The component is housed in a standard 6-pin dual in-line package (DIP-6), facilitating through-hole mounting on printed circuit boards. This device supports signal conversion between balanced and unbalanced lines, serving as a critical interface element in radio frequency circuits requiring specific impedance matching across the specified bandwidth.

Feature Summary

• Provides balanced-to-unbalanced signal conversion
• Supports 1:16 impedance transformation ratio
• Operates within 300 kHz to 120 MHz frequency range
• Utilizes 6-pin DIP package for through-hole integration

Applications

• RF signal transmission interfaces
• Wireless communication equipment
• Impedance matching networks
• Balanced line driver circuits

Procurement Notes

Verify the component's active status and RoHS compliance before procurement. Confirm that the 6-pin DIP package matches the target PCB footprint and soldering process requirements. Ensure the 300 kHz to 120 MHz operational range aligns with the system's frequency specifications. Validate that the 1:16 impedance ratio meets the circuit design constraints for proper signal integrity.

Selection Notes

Select this balun when a 1:16 impedance transformation is required between balanced and unbalanced sections of an RF circuit. The 6-pin DIP form factor is suitable for prototyping or applications where surface-mount space is limited. Consider the 300 kHz to 120 MHz bandwidth to ensure compatibility with the intended signal frequencies. Evaluate thermal and mechanical stability needs relative to the through-hole mounting method.
