Part Number Breakdown
The ELR16FT1R00DES is a metal film chip resistor from Ellon's ELR series. In the part number, "ELR" denotes the metal film resistor product line, "16" corresponds to the 1206 package size (3.2mm × 1.6mm), "F" indicates a ±1% tolerance grade, "T" typically refers to the power rating, "1R00" specifies the 1Ω resistance value, and "DES" serves as the suffix code for version and packaging differentiation. This model belongs to Ellon's anti-surge metal film chip resistor family, featuring high power density and low temperature coefficient characteristics.
Core Product Features
High Power Density in Compact Footprint
Despite its 1206 package, the ELR16FT1R00DES delivers a 1W power rating—far exceeding conventional 1206 thick-film resistors that typically handle only 0.25W. This is achieved through advanced metal film processing and optimized thermal design, enabling engineers to drive higher current in space-constrained layouts.
Low Temperature Coefficient Metal Film Technology
With a temperature coefficient of resistance (TCR) at ±50ppm/℃, this resistor exhibits minimal resistance variation across wide temperature ranges. Metal film materials inherently offer superior thermal stability compared to thick-film alternatives (which usually exceed ±100ppm/℃), making them ideal for precision current sensing and voltage divider applications where drift must be tightly controlled.
High Precision Resistance Control
The ±1% tolerance ensures excellent batch-to-batch consistency. Combined with the standard 1Ω value, it suits circuit nodes requiring accurate current sampling or impedance matching. Metal film deposition processes enable far tighter resistance control than carbon film or standard thick-film methods.
Surge Withstand Capability
As part of the ELR series, this model demonstrates strong anti-pulse and surge withstand capabilities. It can tolerate transient current spikes during circuit startup or abnormal conditions, reducing the risk of open-circuit failure and improving overall system reliability.
Environmental Compliance
The product complies with RoHS and REACH directives, meeting the material compliance requirements for automotive, medical, and export-oriented applications in the EU and global markets.
Typical Application Scenarios
Industrial Power and New Energy
In switching power supplies, inverters, and EV charging equipment, the 1206 1R 1W resistor serves as a current sense element. At 1A current, it produces a 1V drop—easily sampled by downstream ADCs—while the 1W rating provides margin for short-term overload conditions.
Automotive Electronics
Automotive ECUs, battery management systems (BMS), and motor drives demand components with high thermal stability and reliability. The ±50ppm/℃ TCR ensures sampling accuracy remains stable across the automotive temperature range of -40℃ to +125℃.
Outdoor Lighting and Industrial Control
LED drivers, outdoor luminaire controllers, and PLC modules operate in environments with large temperature swings. The high stability of metal film resistors minimizes control errors caused by resistance drift, extending equipment service life.
Home Appliances and Consumer Electronics
In air conditioner inverters, washing machine motor drives, and power adapters, this model functions as a current-limiting or sense resistor. Its high power density helps reduce PCB area and overall BOM cost.
Competitive Advantages
Versus Thick-Film Resistors: Metal film technology delivers lower TCR and higher precision that thick-film solutions cannot match. While the unit price is slightly higher, the total cost of ownership is often lower in precision and long-life applications.
Versus Alloy Current Sense Resistors: At 1Ω, this sits in the mid-to-high resistance range where alloy resistors (typically used for milliohm-level sensing) become prohibitively expensive and complex to manufacture. The ELR16FT1R00DES fills the market gap for high-power precision resistors in the 1Ω range using metal film technology.
Versus Import Brands: As a quality domestic manufacturer, Ellon offers significant price and lead-time advantages over international competitors like Yageo, Vishay, and KOA, with faster local technical support suitable for both small-batch prototyping and high-volume production.
