• Provides station protection and test access points for telephone lines
• Features dual winding construction with low radiation characteristics
• Supports configurations for multiple POTS lines or combined POTS/DSL setups

Applications

• POTS line protection
• DSL line integration
• Station protection circuits
• Test access point implementation

Procurement Notes

Verify the specific suffix code against the official Bourns datasheet to confirm exact electrical parameters and mechanical dimensions. Confirm availability status as the part may be listed in obsolete documentation archives. Ensure the selected variant matches the required voltage rating and mounting style for the target application design.

Selection Notes

Select this component when designing circuits requiring integrated protection for analog telephone lines. Consider the 1000Vrms dielectric strength and operating temperature range for environmental compatibility. Evaluate the radial through-hole mounting requirement against board space constraints. Verify compatibility with DSL signaling if multi-service line support is necessary.

Part Context

The 7004 series belongs to Bourns' network interface device portfolio, which includes components like the 7004C series. These devices are engineered for telecommunications infrastructure, providing essential signal conditioning and protection functions. The series represents a specialized segment of magnetic components focused on line isolation and safety compliance.

Replacement Considerations

Consult the official Bourns obsolete data sheets for confirmed substitute part numbers. Cross-reference specifications such as inductance, DC resistance, and physical footprint before substitution. Verify that any alternative component meets the same dielectric strength and thermal performance requirements.
