Power And Operating Modes

• Active current: Not characterized in seed; extract active current from datasheet tables.
• Sleep / standby current: Not characterized in seed; extract sleep/standby current from datasheet tables.
• Supply rails: Not characterized in seed; capture allowed supply rail range from datasheet.
• Notes: Seed values are search hints only. Verify power modes, rail limits, startup requirements, and reference design passives from the datasheet.

Procurement Classification

• JLC class: Extended Part
• JLC note / assembly basis: EasyEDA/JLC verified common drivers, isolation, and actuation seed
• Assembly status: jlc_extended
• Price-break table: Not captured in seed. Store only timestamped price-break snapshots when intentionally refreshed.
• Live stock: intentionally not stored as durable selection data; refresh externally before ordering.

• Product URL: https://item.szlcsc.com/datasheet/HFD4%252F5-SR/65466.html
• Datasheet-derived notes: Not extracted yet. Use PDF extraction to fill power modes, absolute maximums, pin functions, package variants, and reference design requirements.

Selection Notes

• Good for: reuse when package, electrical ratings, footprint, and assembly class match the project constraints
• Avoid when: Not captured yet.
• Known layout constraints: Verify package land pattern, decoupling requirements, thermal pad, RF keepouts, crystal routing, and boot straps from the datasheet.
• Equivalent search hints: match category signal-relay, interfaces gpio, package SMD,10x6.5mm, and EasyEDA footprint UUID 8f4578d0ed1f46c5b26c87c14afd93a4.
