Key Parameters and Features:
1. Isolation Transformer: TPHR9003NL,L1Q is designed to provide electrical isolation between input and output, crucial for safety and noise suppression in power circuits.
2. High Voltage Isolation: It offers high voltage isolation capabilities, making it suitable for applications that require separation between high-voltage and low-voltage components.
3. Inductance and Turns Ratio: The transformer's inductance and turns ratio are critical parameters that determine its voltage transformation capabilities.
4. Surface Mount Design: The "L1Q" in the part number suggests a surface mount package, making it suitable for compact and automated assembly processes.
Application Scenario: PoE (Power over Ethernet) Isolation Transformer
In this scenario, we will use the TPHR9003NL,L1Q in a PoE application to provide electrical isolation and voltage transformation for an Ethernet-connected device.
Circuit Connection:
1. Primary Coil Connections (Pins 1, 2):
- Pin 1: Connect to the positive side of the power source (e.g., PoE switch).
- Pin 2: Connect to the negative side of the power source.
2. Secondary Coil Connections (Pins 4, 5):
- Pin 4: Connect to the load device (e.g., an Ethernet device).
- Pin 5: Connect to the load device's ground reference.
Design Considerations:
1. Turns Ratio: Determine the required turns ratio of the transformer to achieve the desired output voltage from the PoE source voltage.
2. Isolation Requirements: Ensure that the transformer provides adequate isolation to meet safety and noise immunity standards for PoE applications.
3. Current Rating: Select a transformer with an appropriate current rating to handle the power requirements of the load device.
4. Core Material: Consider the core material (e.g., ferrite) and design to minimize core losses and optimize the transformer's performance.
5. EMI/EMC: Implement EMI/EMC (Electromagnetic Interference/Electromagnetic Compatibility) measures to reduce electromagnetic interference in the circuit.
6. Temperature: Monitor and manage temperature rise in the transformer to prevent overheating and ensure long-term reliability.
7. Physical Mounting: Securely mount the transformer to the PCB (Printed Circuit Board) to prevent mechanical stress on the component.
By addressing these design considerations and properly connecting the TPHR9003NL,L1Q in the PoE circuit, you can effectively utilize the transformer to provide electrical isolation and voltage transformation in PoE applications, meeting the requirements for safety and performance while adhering to key design considerations for power transformer applications.
