The Hammond Manufacturing 560J is a broadcast-quality audio transformer designed for collector-to-line or line-to-base circuit applications. It features through-hole PC board mounting with a minimum pin length of 0.187 inches. The unit provides a 150 mW power rating within ±1.5 dB tolerance across a frequency range of 300 Hz to 50 kHz. Constructed with rugged black epoxy potted material in a molded case, it ensures durability. The component operates as a single-channel device suitable for general-purpose and push-pull tube output circuit replacements.
Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct pin configuration and mounting specifications. Confirm that the epoxy potting material meets environmental requirements for the intended deployment. Cross-reference the datasheet revision date to validate performance parameters such as power rating and frequency response before finalizing procurement orders.
Select this component when a robust, potted audio transformer is required for tube-based amplifier designs. Ensure the PCB layout accommodates the through-hole mounting style and the specified minimum pin length. Verify that the 150 mW power rating aligns with the system's signal levels. Consider the physical dimensions of the molded case during mechanical integration planning.
The 560J belongs to the 560 series of audio transformers manufactured by Hammond Manufacturing. This series focuses on broadcast-quality components utilizing high-quality magnetics. The 560J specifically targets applications requiring reliable performance in tube output stages, distinguishing itself from other series through its specialized potted construction and dedicated impedance matching capabilities for audio signals.
The 560L serves as a related variant within the same product family. Verify compatibility regarding impedance ratios and physical footprint before substituting. Ensure the replacement part maintains the necessary broadcast quality standards and mounting interface requirements for the existing circuit design.
