CRH1206F16K0P05Z 16kΩ 0.5W High Power Thick Film Chip Resistor with ±1%

CRH1206F16K0P05Z 1206 16K 0.5W Ever Ohms High Power Chip Resistor

Part Number Breakdown

CRH1206F16K0P05Z is a standard ordering code from the EVER OHMS CRH high power thick film chip resistor family:

The 1206 16K 0.5W Ever Ohms resistor doubles the power handling of a conventional 0.25W part in the same footprint, which is the defining feature of the "power upgraded" CRH design.

Key Electrical Parameters

• Nominal resistance: 16kΩ, tolerance ±1%
• Rated power: 0.5W at 70°C, linearly derated above 70°C to zero at 155°C
• TCR: typically ±100ppm/°C in this resistance range (some datasheet revisions list ±200ppm/°C; verify against the latest factory document)
• Operating temperature: -55°C to +155°C
• Maximum working voltage: 200V (certain CRH1206 specifications state 250V); short-time overload 400V for 5s
• Insulation resistance: ≥10GΩ
• Construction: 96% alumina substrate, ruthenium oxide thick film paste, high temperature firing, glass glaze protection
• Terminations: nickel barrier plus tin-silver-copper outer plating, resistant to sulfurization and electrochemical migration
• Packaging: tape and reel, 5000pcs per reel, compatible with reflow and wave soldering

At 16kΩ and 0.5W, the rated current is about 5.6mA and the rated terminal voltage about 89.4V. Applying 200V across this resistor would dissipate 2.5W, far above rating, so in high voltage divider designs the 1206 16K 0.5W Ever Ohms resistor is power limited rather than voltage limited, and power dissipation must be the first constraint checked.

Reliability and Construction

• The fired thick film layer combined with the glass glaze keeps resistance drift under control in 85°C/85%RH damp heat, and resistance change after 1000 hours of rated load life testing is generally within 0.5%.
• The three layer termination structure resists sulfur induced open failures in industrial atmospheres and battery pack interiors.
• Selected production lots can meet AEC-Q200; request lot specific certification from the distributor.

Typical Applications

• Power supply feedback and divider networks in DC-DC and AC-DC modules, where ±1% tolerance holds the divider ratio stable and the 0.5W headroom absorbs startup and load transient dissipation
• Pull-up and pull-down resistors, optocoupler input current limiting, comparator reference dividers
• RC low pass filtering and timing networks, where wide temperature TCR behaviour keeps the cutoff frequency stable
• Gate drive series or pull-down resistors for MOSFET and IGBT stages, and output dummy loads
• Industrial and new energy circuits: PLC I/O, inverter signal dividers, BMS sampling and balancing, PV inverter signal conditioning

Derating and Layout Guidance

• Derate above 70°C ambient and keep actual dissipation below 60% of rating at 125°C.
• Allow 1.5 to 2 times power margin in the budget.
• Add copper pours under the pads with thermal vias to inner or bottom layers, and follow lead-free reflow profiles to avoid repeated rework that can lift terminations.

Cross References

• Direct equivalents include Vishay CRCW1206 16K0 FKEAHP (0.5W) and UniOhm HP06W2F1602T5E (1/2W).
• The Yageo RC1206FR-0716KL is only 0.25W and requires two parts in parallel or a revised thermal design.
• When substituting, verify TCR, working voltage, termination plating and moisture sensitivity level, not just resistance and case size.

Sourcing

• Shenzhen Shunhai Technology Co., Ltd.: authorized distributor for EVER OHMS, supplying the full thick film and thin film chip resistor range plus alloy shunt resistors, with factory datasheets, lot traceability and RoHS/REACH documentation, plus support for alternate part selection.
• Huanian Mall: online electronic component platform supporting BOM matching and online quotation, convenient for small batch multi-part purchases and prototype restocking.

Confirming resistance, tolerance, power, TCR, working voltage and temperature range at the outset avoids costly requalification later.
