URA series provides dual symmetric outputs (e.g. ±12V or ±5V) for analog circuits requiring bipolar supply. Choose URB for digital logic, URA for op-amp and analog front-end circuits.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eQ: How does the 5W variant compare to the 6W variant (URB2403YMD-6WR3)?\u003c\/b\u003e\u003cbr\u003eA: The 6W variant (1400mA output) provides 17% more current capacity for higher-load designs. The 5W variant (1200mA) covers most MCU and sensor board requirements at lower cost.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eQ: Can this module be used in 12V systems?\u003c\/b\u003e\u003cbr\u003eA: Yes — the 9-36V input range covers 12V nominal systems. The same module works in both 12V and 24V DC bus environments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eQ: What external components are recommended?\u003c\/b\u003e\u003cbr\u003eA: Input-side bulk capacitor (47-100µF) and output-side filter capacitor (100µF ceramic + 10µF electrolytic) per Hi-Link application note for optimal ripple performance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eQ: Is this module compatible with other URB_YMD variants?\u003c\/b\u003e\u003cbr\u003eA: Yes — the entire URB_YMD family shares a consistent SIP-7 footprint. You can swap between 3.3V, 5V, 12V, 15V, 24V output variants on the same PCB without layout changes.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Hi-Link","offers":[{"title":"Default Title","offer_id":45365227061446,"sku":"HLK-URB2403YMD-5WR3","price":4.46,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0621\/0050\/4774\/files\/2025_9a52ad69-81c0-4f76-bb03-4dc231822615.webp?v=1770837043","url":"https:\/\/upenelab.com\/products\/hi-link-urb2403ymd-5wr3","provider":"OpenELAB Technology Ltd.","version":"1.0","type":"link"}
