What are the key features of CN1J4KTTD334J?
- 330 kΩ ±5% isolated resistor array with 4 elements in a compact 0603 SMD package, delivering 0.063 W per element power dissipation
- Isolated network topology allows each of the 4 resistors to carry independent signals without cross-coupling, ideal for pull-up or pull-down bus termination
- RoHS compliant and Pb-free (JESD-609 e3) construction for lead-free reflow compatibility and global regulatory compliance
What is CN1J4KTTD334J used for?
The CN1J4KTTD334J is commonly used for pull-up or pull-down termination on digital signal buses and microcontroller I/O lines where a 330 kΩ high-impedance bias is needed across 4 independent channels. Its compact 0603 isolated array form reduces board space compared to four discrete 0603 resistors while maintaining per-element independence for logic level setting in SPI, I2C, or GPIO interfaces. The 0.063 W per element rating suits low-power signal conditioning in consumer electronics, industrial sensors, and communication modules.

Frequently Asked Questions
What resistance value and tolerance does the KOA Speer CN1J4KTTD334J provide in its 0603 isolated array?
The CN1J4KTTD334J offers 330 kΩ resistance with ±5% tolerance across 4 isolated elements in a 0603 SMD package, each rated at 0.063 W power dissipation. This high-impedance value is suited for weak pull-up or pull-down bias on high-impedance inputs such as MOSFET gates, ADC references, or CMOS logic I/O pins requiring minimal leakage current.
How does the isolated network topology of CN1J4KTTD334J differ from bussed resistor arrays for bus termination?
In an isolated network like the CN1J4KTTD334J, each of the 4 resistor elements has independent terminals with no shared bus connection, allowing each 330 kΩ resistor to serve a separate signal line. A bussed array shares one common rail among all elements, which suits single-ended pull-up buses but would create unintended coupling on independent multi-channel 330 kΩ termination networks needed in differential or mixed-signal designs.
What are the compliance certifications for the CN1J4KTTD334J, and why do they matter for global supply chains?
The CN1J4KTTD334J carries RoHS compliance and a JESD-609 e3 Pb-free rating, confirming it meets the European Union's restriction on hazardous substances for electronics containing no lead above 0.1% by weight. This certification is required for products sold in the EU and increasingly mandated in Asian and North American markets, ensuring the 0603 330 kΩ isolated array can be incorporated into globally distributed designs without regulatory barriers.
