ATQ27-4733

Overview

The ATQ27-4733 is a pulse transformer manufactured by Allied Components International, designed for through-hole mounting. It utilizes the ATQ27 package configuration with seven pins. The component features a turns ratio of 1:0.182:0.136:0.136:0.136 and provides an inductance of 210µH with a tolerance of ±5%. The maximum leakage inductance is specified as 9.0µH. It operates within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Seven-pin through-hole design utilizing the ATQ27 package format
• Specific multi-tap turns ratio configuration for signal isolation
• Industrial-grade thermal stability suitable for wide temperature environments

Applications

• Pulse signal transmission in electronic circuits
• Isolation barriers in industrial control systems
• Power supply management circuitry requiring specific impedance matching

Procurement Notes

Verify the exact pinout configuration against the official datasheet before integration, as the seven-pin layout supports multiple secondary taps. Confirm that the 210µH primary inductance meets the specific frequency response requirements of the target application. Ensure the operating environment remains within the specified -40°C to +85°C range to maintain performance integrity and reliability standards defined by the manufacturer.

Selection Notes

Select this component when a precise multi-tap isolation transformer is required for pulse applications. The specific turns ratio dictates its suitability for voltage scaling or impedance transformation tasks. Consider the physical dimensions of the ATQ27 package for PCB layout constraints. Verify that the leakage inductance specifications align with the switching speed requirements of the driving circuitry to prevent signal distortion.

Part Context

This part belongs to the ATQ series of transformers, which are characterized by their use of MnZn power ferrite materials. The ATQ27 variant specifically refers to the bobbin and core assembly size, providing a standardized footprint for various winding configurations. This series is commonly used in applications requiring reliable magnetic coupling with compact physical profiles.

Replacement Considerations

Direct substitutes must match the 7-pin ATQ27 form factor and the specific 1:0.182:0.136:0.136:0.136 turns ratio. Generic replacements may not replicate the exact 210µH inductance or 9.0µH leakage inductance limits. Cross-reference with other manufacturers offering ATQ-style pulse transformers only if electrical parameters are identical.
