Psf 16211

The phrase PSF-16211 (specifically the PSF-16211 T) refers to a 10/100Base-T Single Port LAN Transformer, a critical electronic component used for signal isolation and noise filtering in Ethernet interfaces LcscDatasheet4U. It is primarily manufactured by CND-tek (also known as T-CND) and Shenzhen Magnetic (PPT) LcscAlldatasheet.

Product Insights & Specifications

This component is a small-signal pulse transformer designed for Fast Ethernet (100 Mbps) applications AlibabaLcsc.

* Key Specs: 350µH minimum inductance, 1CT:1CT turns ratio, and 1.5kV isolation voltage LcscDatasheet4U.

* Package: Standard SMD-16P (12.7mm x 7.0mm), making it suitable for compact PCB designs in routers, switches, and network interface cards LcscDigi-Electronics.

* Real-world Applications: It is frequently found on the mainboards of consumer electronics such as Aiwa LED TVs and Openbox satellite receivers, as well as industrial control boards like the Whatsminer M21S/M20S cryptocurrency miners RedditEbayRadius.

Market Trends & Pricing

The market for these transformers is driven by the steady demand for legacy 10/100 Mbps Ethernet in smart home devices and industrial automation VolzaAccio.

* Pricing: Wholesale prices are highly volume-sensitive, ranging from approximately $0.12 to $0.50 per unit AlibabaLcsc. Bulk quantities (5,000+ pieces) can drop as low as $0.11 Lcsc.

* Stock & Availability: Current retail stock is relatively tight at major distributors like LCSC (only 5 units remaining in one instance), though larger stocks (2,300+ units) are held by specialized electronics brokers LcscDigi-Electronics.

* Competition: The PSF-16211 faces strong competition from functional equivalents like the Pulse Electronics H1102NL series and Mentech G24T01D, which are often preferred for new designs due to broader availability Lcsc.

Technical Failure Context

Repair technicians often encounter this component in devices exhibiting network connectivity issues or boot-loops (though the latter may sometimes involve misidentification of nearby SPI flash chips in forum discussions) RedditBadcaps. In thermal-heavy environments, such as LED TV mainboards, the transformer can suffer from solder joint degradation due to constant thermal cycling Badcaps.
